Abstract

Abstract

With the continuous construction of Global Navigation Satellite System (GNSS), the location-based service (LBS) of smart phones has rapidly developed. In this paper, several commonly used smartphone are selected as research objects, such as Samsung S9+(Exynos), Huawei Mate30, Huawei P40 Pro. the measurement receiver UR4B0-D from BDStar Navigation is used for synchronous static observation experiment. the GNSS raw data quality of Android smartphone is analyzed from the aspects of satellite visibility, carrier-to-noise ratio (CNR), satellite altitude angle, multipath error and so on. The results show that there are obvious differences in observation capabilities and data quality among different smartphones. Android smartphones have poor data quality and low CNR. The CNR of Android smartphones has no obvious relationships with the satellite altitude angle. In addition, multipath error is one of the main errors that affect the high-precision positioning of Android smartphones.
